Overview
There are no echocardiography and ultrasound findings associated with Bell's palsy. However, an x-ray may be helpful in the diagnosis of other causes of facial nerve palsy.
Echocardiography and ultrasound
- There are no echocardiography findings associated with Bell's palsy.
- Ultrasound of the facial nerve may be used to predict functional outcomes in patients with Bell's palsy.[1]
- Ultrasound may show increase in facial nerve diameter and side-to-side difference in diameter in patients with facial nerve palsy compared to controls.[2]
- The diameter of the affected side may be significantly larger than that of the healthy side in patients with Bell's palsy.
- Ultrasound also may be helpful in the diagnosis of other causes of facial nerve palsy.[2]
